Torsion test rigs

Torsion test rigs are used to test components under variable conditions.

Torsion test rigs allow the testing of components under torque (Nm). This kind of testing uses a variety of drive systems and actuators according to requirements, depending on whether a component should be subjected to static or dynamic stress.

  • MMFTR – Multi-modular function test rig

    Multi-modular function test rigs (MMFTR) enable torsion tests on components under variable test conditions. These include test procedures such as impact testing, snap start, double fatigue, rotational fatigue, differential testing and clutch testing.

  • High-speed test rig for determining friction behaviour

    There are many factors that influence how seals behave under friction. This high-speed test rig is used to investigate the effect of speed, temperature, medium, pressure and misalignment on seal friction behaviour.
